The verdict in three sentences
For a 110-employee civil works contractor in Dublin, every week lost between the site measurement and the monthly valuation pushes back tens of thousands of euros in cash collection. Off-the-shelf construction software at 40-120 EUR per user per month covers most needs if your processes are standard, but it often struggles to integrate with your estimating software and your valuation templates. Custom development at 40,000-100,000 EUR, delivered in 4 to 6 months, pays off when it saves more than 6 hours a week per site manager and cuts measurable invoicing delays.
The real cost of paper and spreadsheet site tracking
In a typical Dublin civil works contractor, the senior site manager spends around 6 hours a week retyping progress reports, compiling quantities, preparing monthly valuations and answering the quantity surveyor. Foremen send quantities by photo or text message, then everything is copied into Excel before being keyed into the estimating and invoicing software.
| Source of loss | Observed volume (2026 order of magnitude) | Estimated annual cost |
|---|---|---|
| Retyping site reports | 3 h/week per site manager | 7,500 EUR per site manager |
| Preparing valuations | 2 h/week | 5,000 EUR |
| Chasing and corrections after QS disputes | 1 h/week | 2,500 EUR |
| Average delay in issuing valuations | 8 to 12 days | Tied-up cash |
| Unbilled quantity variances (forgotten variations) | 0.5 to 1.5% of site revenue | 20,000 to 60,000 EUR on 4 M EUR |
| Disputes over untracked variations | 2 to 4 per year | 5,000 to 15,000 EUR |
The loaded hourly cost of a site manager in Dublin is around 50 EUR in 2026. With 5 site managers, retyping alone represents nearly 75,000 EUR a year of skilled time spent on tasks with no added value.
Construction software package or custom build: 2026 comparison
The figures below are 2026 market estimates, in EUR excluding VAT, hardware excluded. They are not a Kolonell price list.
| Criterion | Off-the-shelf construction software | Custom development |
|---|---|---|
| Entry cost | 2,000 to 8,000 EUR setup | 40,000 to 100,000 EUR |
| Subscription | 40 to 120 EUR per user per month | No licence |
| Hosting and maintenance | Included | 600 to 1,500 EUR per month |
| Time to go live | 4 to 10 weeks | 4 to 6 months |
| Integration with existing estimating software | Standard connector or CSV export | Dedicated API, price library reused |
| Valuation templates (bills of quantities, variations, 5% retention) | Generic templates | Your exact templates, approved by finance |
| Offline site entry | Depends on vendor | Built into the specification |
| 5-year cost for 25 users | 15,000 to 45,000 EUR | 76,000 to 190,000 EUR |
On paper, the package wins over 5 years. Custom becomes profitable when your company has strong specifics: quantities per pour phase, cumulative progress per work package, price adjustment indices, integration with an ERP or document system already in place. That is often the case above 100 employees.

| Module | Expected gain | Priority |
|---|---|---|
| Mobile site report (photos, weather, headcount) | -2 h/week per site manager | Essential |
| Quantity entry per element and work package | Reliable, traceable measurements | Essential |
| Automatic monthly valuation | Issued on day 2 instead of day 10 | Essential |
| Variation and extra works tracking | +0.5 to 1% of revenue billed | Strongly advised |
| Sync with estimating software | Zero retyping | Strongly advised |
| Margin dashboard per site | Weekly control | Phase 2 |
A hybrid approach works well: a custom measurement and valuation module connected by API to the estimating software your teams already know.
Mini case study
Ciaran, senior site manager at a 110-employee civil works contractor in Dublin (revenue 18 M EUR), supervises 4 site managers. Assumption: the custom tool saves each of them 5 hours a week over 45 weeks, i.e. 5 x 5 x 45 = 1,125 hours, valued at 50 EUR: 56,250 EUR a year. Valuations issued 8 days earlier on 1.5 M EUR billed per month free up around 400,000 EUR of cash, i.e. 16,000 EUR of overdraft interest avoided at 4%. By recovering 0.5% of forgotten variations, i.e. 90,000 EUR, the 80,000 EUR project pays back in under 6 months. This scenario is illustrative.
FAQ
How much does site progress software cost for a civil works SME in 2026? A construction package costs 40 to 120 EUR per user per month, i.e. 12,000 to 36,000 EUR a year for 25 users. Custom development ranges from 40,000 to 100,000 EUR, plus 600 to 1,500 EUR a month for maintenance.
How long does it take to deploy a measurement and valuation tool? Allow 4 to 10 weeks for a package and 4 to 6 months for a custom tool. A 6-week pilot on 2 sites is recommended before full rollout.
Can we keep our current estimating software? Yes, in most cases, through an API or a scheduled file exchange. Integration usually accounts for 15 to 25% of the custom budget.
Will foremen actually use it? Adoption depends on mobile entry taking under 3 minutes per report and on offline mode. Plan 2 half-day training sessions per team and a site champion.
Does the software handle retention and price adjustment? A custom tool builds in the 5% retention, price indices and advance payments according to your contracts. Packages often do it too, but with less flexible templates.
